Alpes Lasers - Packaging Services in HHL Housing

The HHL housing from Alpes Lasers is a compact, sealed enclosure specifically designed for continuous wave (CW) or pulsed lasers. It is ideal for short-run integrations and challenging environments, offering a smaller alternative to the LLH housing. The HHL is equipped with a Peltier junction and an NTC temperature sensor (model 10K4CG), making it compatible with the TC3 or other temperature control systems. Its heat dissipation relies on thermal contact with a copper base, with the capacity influenced by operational modes and environmental conditions. For laser applications requiring optical fiber outputs, the HHL can be configured with pigtailed optical fibers, including Indium Fluoride fibers for wavelengths up to 5 μm. The internal Peltier cooler is available in three configurations: 1-stage, 2-stage, and high power (HP). The appropriate cooler is selected based on operational requirements, with the HP variant suited for higher dissipation needs. The efficiency of the Peltier cooler is demonstrated in comparative performance graphs, juxtaposed with the larger LLH housing.
